As commercial aerospace enters a new low-cost and reusable track, a Chinese private enterprise is writing a new chapter in rocket manufacturing with stainless steel. On January 7th, Jianyuan Technology officially started construction of its rocket assembly, testing, and recycling base in Qiantang District, Hangzhou, Zhejiang Province, marking the substantive construction stage of the first stainless steel rocket super factory in China for offshore recycling. This is not only the foundation of a factory, but also a crucial step for China's commercial aerospace industry to move towards scale and industrialization.

Stainless steel rocket, disruptive path

Jianyuan Technology has chosen a technology route that is different from the mainstream - a stainless steel arrow body paired with liquid oxygen methane propellant. This solution can significantly reduce manufacturing costs and maintenance difficulties while improving structural strength and high temperature resistance. Its core product, the Yuanxing-1 rocket, is designed to be reusable up to 20 times and has completed key validation throughout the entire process, including sea flight recovery and splash down recovery joint testing, by 2025. The verification arrow has a diameter of 4.2 meters and a height of approximately 26.8 meters, successfully completing a 125 second flight and verifying the feasibility and reliability of the stainless steel arrow body.

Super factory, aiming for large-scale production

The total investment of the project under construction this time is as high as 5.2 billion yuan, and the first phase covers an area of 108 acres. The core goal of a factory is not only manufacturing, but also building a full cycle capability for recycling and reuse. After completion, it will form a large-scale production capacity of 25 Yuanxing-1 rockets per year. More importantly, the factory will integrate a complete process system for rapid detection, maintenance, and reuse of rockets after recovery, laying a solid hardware foundation for future high-frequency and low-cost launch services.

Commercial aerospace, opening a new chapter in the industry

This base is not only the first stainless steel rocket super factory in China, but also the first production capacity base dedicated to the recycling and reuse of rockets at sea. Its construction signifies that China's commercial aerospace industry is rapidly shifting from technology validation to large-scale operation. Through recyclable and reusable technology, the launch cost will be significantly reduced, which will effectively leverage downstream application markets such as satellite Internet, space tourism, space experiments, promote the maturity and development of the entire commercial aerospace industry ecology, and provide important support for China to seize the new track of space economy.
